Abstract: A torque limiter, in particular for a surgical instrument, comprises a rotor (4) and a cage (8) arranged coaxially in relation to the rotor (4), the cage has at least one rolling body holder (7) with a rolling body (6) held in it, the rolling body holder (7) has at least one side wall which is arranged at an oblique angle relative to a circumferential direction of the cage (8).

Abstract: An injection molding machine with a vertically displaceable closing unit, comprises a plate-like lower yoke as the counterpressure plate; a plate-like upper yoke as the stationary mold clamping plate; at least three vertically aligned struts connecting the lower yoke and the upper yoke with each other in a force-locked manner; as well as another plate-like element serving as the displaceable mold clamping plate, which is displaceable on the struts by one or more driving cylinders having a small cross section and a large stroke length. The displaceable mold clamping plate is displaceable by one or more driving cylinders stopped on the displaceable mold clamping plate and on the counterpressure plate, such that molding tool halves arranged on surfaces of the mold clamping plates can be driven from a maximum spacing into a position of mutual abutment, and vice-versa.
